The issue has already been reported, it's not really new.  The code that
handles interfaces and addresses is different in ospfd and ospf6d.
I recently tried to sync that code but there were a few differences that
made it more difficult than expected.

ospf6d exits after ospf6ctl reload

2017-03-13 Thread Remi Locherer 
Hi,

ospf6d does not like beeing reloaded and exits.

Below an example on -current running in VMM. I first noticed it
on an OpenBSD 6.0 amd64 router on real hardware.
